5. Sąranka ir diegimas
The STVP-932 is designed for DIN rail mounting within an electrical enclosure. Ensure proper ventilation and clearance around the device.
5.1 Montavimas
Attach the protector to a standard 35mm DIN rail by snapping the clips on the back of the device onto the rail. Ensure it is securely fastened.

5.2 Sujungimo schema
Follow the wiring diagram carefully to connect the STVP-932 to your three-phase electrical system. The device has 'IN' terminals for incoming power (L1, L2, L3, N) and 'OUT' terminals for protected outgoing power (L1, L2, L3, N).

Prisijungimo žingsniai:
- Connect the incoming three-phase power supply (L1, L2, L3, N) to the 'IN' terminals of the STVP-932.
- Connect the 'OUT' terminals (L1, L2, L3, N) of the STVP-932 to the load or downstream circuit protection devices (e.g., air circuit breaker).
- Įsitikinkite, kad visos jungtys yra tvirtos ir saugios, kad išvengtumėte atsilaisvinusių kontaktų ir perkaitimo.

Reguliuojami parametrai apima:
- Per tomastage protection value (Uvo)
- Per tomastage atkūrimo vertė
- Per tomastage apsaugos veikimo laikas
- Nepakankamas tomastage protection value (Uve)
- Nepakankamas tomastage atkūrimo vertė
- Nepakankamas tomastage apsaugos veikimo laikas
- Trifazis ttage unbalance protection value
- Trifazis ttage unbalance protection action time
- Delay time after power-on
- Fault recovery delay time
6.3 Reset Mode Selection
The device supports different reset modes. Consult the English manual included in the package for detailed instructions on selecting the appropriate reset mode for your application.
6.4 Fault Inquiry and Factory Reset
The device allows for fault inquiry to review past protection events. A factory data reset option is also available to restore all parameters to their default settings.
7. Problemų sprendimas
This section provides guidance on common issues you might encounter with the STVP-932.
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| Device trips frequently | ttage fluctuations (over/under voltage), phase unbalance, incorrect settings. | Check power supply stability. Adjust protection thresholds (Uvo, Uve) and action times. Verify load balance across phases. |
| Nėra ekrano / Nėra maitinimo | No input power, incorrect wiring, internal fault. | Ensure main power is on. Check input wiring (L1, L2, L3, N). If wiring is correct and power is present, contact support. |
| Device does not reset | Continuous fault condition, incorrect reset mode setting. | Ensure the fault condition has cleared. Check the configured reset mode and recovery delay time. |
| Neteisingas ttage skaitymai | Loose connections, sensor issue. | Verify all wiring connections are secure. If the issue persists, contact support. |
8. Priežiūra
- Regularly inspect the device for any physical damage or signs of overheating.
- Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Periodically check all wiring connections to ensure they remain tight and secure.
